This grotto is located about 12 kilometers south of Luoyang City. The north and south mountains here face each other, and the Yishui River flows through it. From a distance, it looks like a natural gate, so it is also called "Yique". The Longmen Grottoes are located here. It is now a national key cultural relic protection unit.

The Longmen Grottoes were first excavated in the Northern Wei Dynasty, around the time when Emperor Xiaowen of Wei established Luoyang as the capital. The grottoes were excavated for a long time, and later went through the Eastern Wei, Western Wei, Northern Qi, Northern Zhou, Sui, Tang, Five Dynasties, Song, etc. According to statistics, there are more than 2,100 cave niches and more than 100,000 statues in the two mountains. The largest statue is 17.17 meters high. The smallest is only 2 centimeters. In addition, there are more than 40 pagodas and 3,680 statues and inscriptions. There are many caves in Longmen Grottoes, the more famous ones are Binyang Cave, Qianxi Temple, Wanfo Cave, Fengxian Temple, Guyang Cave, etc. Here we only talk about Binyang Cave and Fengxian Temple.

Binyang Cave consists of three caves: the middle, north and south caves. It is a famous cave in the Longmen Grottoes. Binyang Middle Cave is the main cave, located in the northern part of the West Mountain of Longmen. It is one of the two caves built by Emperor Xuanwu of the Northern Wei Dynasty, Yuan Ke, for his parents, Emperor Xiaowen and Empress Dowager Wenzhao. It took 24 years from the first year of Jingming (500) to the fourth year of Zhengguang (523) in the Northern Wei Dynasty. It is the longest carving time, the most labor-intensive and the most magnificent cave among the Longmen statues. The original Buddha, Sakyamuni, is located in the center. The statue is 8.4 meters high. He has a delicate face, a high nose and a big smile. He is the top grade of Chinese stone carving art in the Northern Wei Dynasty. On both sides of the main Buddha stand two disciples and two Bodhisattvas. One Buddha and two Bodhisattvas are carved on the walls on both sides. The top of the cave is carved with ten Jile heavenly beings flying around the lotus cover. Binyang North Cave was first dug during the Northern Wei Dynasty and was not completed until the early Tang Dynasty. The Amitabha Buddha in the center is 7.55 meters high. The backlight of the Buddha looks like a burning flame, but if you look closely, it looks like a gourd pattern. The carving is detailed and vivid, and is a masterpiece of backlit flame patterns on Buddhist statues from the Tang Dynasty. On both sides of the Buddha are engraved Arhats and Bodhisattvas; on both sides of the door are two heavenly kings embossed, with powerful shapes. Binyang South Cave was excavated from the Northern Wei Dynasty to the Sui Dynasty. Amitabha Buddha is engraved in the center, with a plump face and smooth clothing lines. There are countless small and large Buddhist niches in the cave. On the top of the cave, around the lotus cover, there are two donors holding offerings and six celestial beings with flowing clothes, elegant and beautiful.
